hairiness. The opinion prevails also that the yield is 

 not as a rule as satisfactory, and that the plants are more 

 subject to mildew. Werner states, however, that the value 

 of the American seed under German conditions is not yet 

 clear, in spite of the numerous field trials. 



At the Wisconsin Experiment Station in 1901 American 

 medium and mammoth both outyielded European strains 

 from Hungary, England, Steirmark, Transylvania, Russia 

 and Germany, though the hay of the European sorts was 

 better in quality, owing to the plants being less hairy. 

 In 1902 out of 16 American and European strains, the 

 four highest yields were from American 'lots. In 1905 

 out of 22 American and 2 foreign strains, the largest 

 yield, 2.2 tons an acre, was from the Orel strain from 

 Russia. 



At the Maine Experiment Station 29 regional strains 

 of red clover were tested in 1902 on duplicate plots of one- 

 eightieth acre. One plot of each was cut August 30, when 

 the earliest was ready for cutting. The largest yields were 

 obtained in the order given from plots with seed from 

 Minnesota, Bohemia, Indiana, Wisconsin, Brittany and 

 Ohio. In the following season the order of their excel- 

 lence, arranged according to the total yield from two 

 cuttings, was Indiana, Bohemia I, Russia, Bohemia II, 

 Illinois, Indiana, Ohio. 



A test of regional strains conducted cooperatively by 

 the United States Department of Agriculture in 1905 gave 

 the results shown in the accompanying table. In this 

 series, Orel clover gave the highest total yield, as well as 

 the highest at two of the stations. Orel clover yields, 

 however, but one cutting, so the relative ranks of the 

 varieties would undoubtedly be different if the total yields 

 for the season were tabulated :
